                                     PART I

ITEM 1.  BUSINESS.

GENERAL

         The Company is engaged in the development and commercialization of
medical devices designed to inhibit excessive surgical scarring and adhesion
formation following surgery. Postoperative scarring and adhesion formation can
become excessive, binding together tissues and organs causing pain, obstruction
and impairment of function. Further, excessive scarring can obstruct access to
the surgical site, making additional surgery difficult. The Company is engaged
in the development and commercialization of the ADCON family of medical devices
to address such postoperative complications. In addition, the Company is
pursuing the development of drug candidates for the treatment of certain nervous
system disorders, including Alzheimer's Disease, through its strategic alliance
with Janssen Pharmaceutica, N.V. of Belgium ("Janssen"), a wholly-owned
subsidiary of Johnson & Johnson, and cognitive disorders.

         The ADCON family of medical devices are being developed by the Company
to inhibit excess scarring and adhesion formation at the surgical site. The
initial ADCON products are formulated as proprietary resorbable gels for direct
application by surgeons to organs and tissues during surgery to inhibit surgical
scarring and adhesions. ADCON-L is designed to inhibit scarring and adhesion
formation following lumbar disc surgery. ADCON-T/N is designed for use in tendon
and peripheral nerve repair surgeries such as carpal tunnel syndrome and
tenolysis. In addition to ADCON-L and ADCON-T/N, the Company is in earlier
stages of development of several additional ADCON products for use in
pelvic/gynecological, abdominal, cardiac and implant/prosthetic surgeries.
Because of the differences in the body environments in which each of these
product candidates would be used, a number of different formulations may be
required.

         Based on European pivotal clinical studies and other compliance efforts
and the submission of other data, the Company obtained regulatory clearances to
affix CE Marking on ADCON-L and ADCON-T/N thereby allowing ADCON-L and ADCON-T/N
to be marketed in the 15 European Union countries for lumbar disc surgery and
tendon and peripheral nerve repair surgery, respectively. The Company has
entered into distribution agreements and is currently selling both ADCON-L and
ADCON-T/N with independent distributors in Australia, Austria, Belgium, Germany,
Italy, The Netherlands, New Zealand, Scandinavia, Spain, Switzerland and the
United Kingdom. Additionally, in the United States, in February 1997, the
Company received notification that its Premarket Approval Application ("PMA")
for ADCON-L had been accepted for filing by the U.S. Food and Drug
Administration ("FDA"). Pivotal clinical trials are currently being conducted
for both ADCON-L and ADCON-T/N. The Company intends to submit a PMA to the FDA
for ADCON-T/N upon successful completion of the trial.

         The Company is also engaged in the research and development of
therapeutic products for the treatment of certain nervous system disorders,
including Alzheimer's Disease and cognitive disorders. Studies have shown that
certain glial cells and glial-derived factors are consistently associated with
senile neuritic plaques, which are thought to be a key contributor to
Alzheimer's Disease pathology. In October 1994, the Company entered into an
agreement with Janssen to collaborate on the research and development of
therapeutic products to treat Alzheimer's Disease (the "Janssen Agreement"). In
addition, in September 1995, the Company entered into an addendum to the Janssen
Agreement in order to expand the scope of the collaboration. As a result of
screening compounds from Janssen's pharmaceutical library, several potential
lead compounds have been identified.

         The Company's Cognition Modulation program is focused on a class of
compounds designed to act on the histamine H3 receptor in the brain which
regulates sleep/wakeful states and modulates the level of arousal and alertness.
An antagonist to this receptor could lead to enhanced states of alertness for
treating attention deficit hyperactive disorder (ADHD), sleep disorders,
obesity, anxiety and the cognitive deficit in Alzheimer's Disease patients.

ADCON SURGICAL ADHESIONS PRODUCTS

         During the normal healing process following surgery a matrix of scar
tissue forms at the surgical site. In many cases, scar formation results in
surgical adhesions that can become excessive, binding together tissues and/or
organs, causing pain, obstruction and impairment of function. Further, excessive
scarring can obstruct access to the surgical site, making additional surgery
difficult.

         The Company is developing and commercializing the ADCON family of
medical devices to act as a barrier to surgical adhesions at the surgical site.
The initial ADCON products are formulated as proprietary resorbable gels to
inhibit surgical scarring and adhesions for direct application by surgeons to
organs and tissues during surgery.

  ADCON-L

         ADCON-L is formulated as a proprietary resorbable gel which is applied
directly by surgeons to the surgical site following lumbar disc surgery. ADCON-L
provides a physical barrier between the membrane covering the spinal cord and
the back muscles and between the spinal nerve roots and the inner surface of the
vertebral body. This barrier is designed to inhibit excess scarring and
resultant adhesion formation at the surgical site.

         Development and Regulatory Status. Based on the results of a pivotal
clinical trial of ADCON-L in Europe, among other factors, the Company obtained
regulatory clearances to affix CE Marking for ADCON-L in the European Union
countries. The CE Marking for ADCON-L allows the Company to market ADCON-L in
the 15 European Union countries (Austria, Belgium, Denmark, Finland, France,
Germany, Greece, Ireland, Italy, Luxembourg, The Netherlands, Portugal, Spain,
Sweden and the United Kingdom) for lumbar disc surgery patients. Based on the
results of a multicenter pivotal trial in European medical facilities, ADCON-L
received European Union ("EU") regulatory approval for sale of such product
throughout the EU and Australia and New Zealand. In February 1997, the Company
received notification that its PMA for ADCON-L had been accepted for filing by
the FDA. The Company is currently conducting pivotal U.S. clinical trials for
ADCON-L.

  ADCON-T/N

         ADCON-T/N is a proprietary resorbable gel which is applied directly by
surgeons to the surgical site following tendon and peripheral nerve surgeries
such as carpal tunnel syndrome and tenolysis. The formation of adhesions which
bind the tendon to surrounding tissues results in a reduction of the tendon's
ability to glide, thus limiting the range of motion. In the peripheral nervous
system, postsurgical scar formation can lead to scarring and compression of
nerves. The combination of scarring and nerve adhesions can result in loss of
nerve function and pain.

         Development and Regulatory Status. The Company obtained regulatory
clearances to affix CE Marking for ADCON-T/N in the EU based on the results of
European clinical studies submitted to a European designated agency. ADCON-T/N
is now being sold in all major countries in the EU, as well as Australia and New
Zealand for use in tendon and peripheral nerve surgeries. The Company is
currently conducting pivotal U.S. clinical trials for ADCON-T/N. The Company
intends to submit a PMA for ADCON-T/N to the FDA upon the successful completion
of these studies.

  OTHER ADCON PRODUCTS

         The Company is also conducting preclinical studies relating to
applications of its ADCON technology in preventing surgical adhesions in a
variety of other surgical procedures. Potential product candidates are being
developed for use in surgeries where adhesions are common and are known to
create troublesome complications including: (i) pelvic/gynecological surgery,
where adhesions may occlude or otherwise impair the normal function of the
ureters, bladder, uterus or fallopian tubes; (ii) abdominal surgery, where
peritoneal adhesions between organs and/or the abdominal wall may seriously
impair gastrointestinal function; (iii) cardiac surgery, where adhesions may
significantly increase the risk of injury during re-operation; and (iv)
implant/prosthetic surgery,

                                       -2-

<PAGE>   5



where adhesions may compromise the effective performance of a medical device.
Because of the differences in the body environments in which each of these
product candidates would be used, a number of different formulations may be
required.

  MARKETING AND SALES

         Currently, the Company is marketing its ADCON products through
independent medical device distributors. As of December 31, 1996, the Company
has entered into agreements with independent distributors regarding
country-specific sales and distribution rights to ADCON-L and ADCON-T/N in
Australia, Austria, Belgium, Germany, Italy, The Netherlands, New Zealand,
Scandinavia, Spain, Switzerland and the United Kingdom. Discussions with respect
to distributor arrangements in other major countries are ongoing. In December
1996, the Company also signed a development and license agreement with Chugai
Pharmaceutical Co., Ltd. for the exclusive development and sale, after obtaining
necessary governmental approvals, of ADCON-L and ADCON-T/N products in Japan.

         These distribution agreements generally provide the distributors with
exclusive distribution rights in their assigned territory. The agreements
require the distributors to meet specified minimum annual sales targets. In
certain of the distribution agreements, the Company may, upon the expiration of
applicable notice periods, terminate the exclusivity of such arrangement or
terminate the arrangement, as the case may be, in the event such sales goals are
not achieved. The Company provides marketing and advertising support to its
distributors and conducts training seminars for distributor personnel. These
distributors are independent third parties, are not employees of the Company and
are not directly under the control or supervision of the Company, except that
they are subject to the terms and conditions of their respective distribution
agreements. There can be no assurance that the current relationships with
distributors will be successful or that the Company will be able to enter into
similar distribution arrangements in other markets, or that such arrangements
will be available on acceptable terms and conditions to the Company. Furthermore
there can be no assurance that the ADCON products will be successfully marketed
since the Company does not control the distribution of its products and relies
exclusively on third parties for its distribution of products.

  MANUFACTURING AND SUPPLIERS

         The Company does not have any manufacturing facilities and presently
utilizes a sole foreign contractor, European Medical Contract Manufacturing,
located in Nijmegen, The Netherlands, for the manufacture of its commercial and
clinical requirements of ADCON-L and ADCON-T/N. The Company currently purchases
the key components for ADCON-L and ADCON-T/N from suppliers and provides such
components to the contract manufacturer who formulates these components into the
gel for the ADCON-L and ADCON-T/N products. The contract manufacturer is
registered as a subcontractor for the manufacture of pharmaceutical products by
The Netherlands designated agency and is certified to ISO requirements for
manufacture of such products. ISO Certification is an internationally recognized
standard of quality manufacturing. It is, however, the Company's intention to
identify additional manufacturers in the future, including a U.S. based contract
manufacturer. The manufacture of the Company's products is subject to Good
Manufacturing Practices regulations ("GMP") or other requirements prescribed by
the appropriate regulatory agency in the country of use. There can be no
assurance that the Company's current manufacturer will continue to comply with
all applicable regulatory requirements or that such manufacturer will be able to
supply the Company with such products or that the Company will be able to
identify additional manufacturers of its products on terms acceptable to the
Company.

         The Company currently obtains one of the key components for its ADCON
products from a single supplier. The Company also has developed its own
proprietary process to manufacture this key component and is currently
manufacturing it on a pilot basis through a contract manufacturer according to
GMP standards. In addition, the Company is pursuing qualification of additional
suppliers. There can be no assurance that additional suppliers will be
identified or that the key components will be available on terms acceptable to
the Company.

  ADCON RESEARCH AND LICENSE AGREEMENTS

         The Company is a party to a license agreement and a related sponsored
research agreement with a university that provides for a royalty of up to 5% of
revenues from products covered by these agreements. In 1995, a dispute regarding
inventorship of the ADCON products and the rights of the university to receive
royalties from sales of ADCON products arose between Gliatech and the
university. The university has threatened litigation regarding this matter.
Gliatech and the university have had, and are continuing to have, discussions
regarding this dispute. There has been no resolution of this matter. The Company
is not able to make any estimate of costs that may arise as a result of any
outcomes from this dispute and there can be no assurance that the Company will
not be required to pay any costs or royalties or that any costs to the Company,
or royalties that may result, from this dispute will not have an adverse effect
on the Company.

  NERVOUS SYSTEM DISORDERS

         The Company's longer-term research is focused on the development of
therapeutic products for the treatment of nervous system disorders for which the
Company believes existing therapies are inadequate. The Company is presently
pursuing the development of small molecular weight compounds for the treatment
of Alzheimer's Disease and cognitive disorders.

         The Company's strategy is to pursue its nervous system disorder
programs through collaboration with third parties. The Company has entered into
a strategic alliance with Janssen to collaborate on the research, development
and commercialization of certain treatments for Alzheimer's Disease. To date,
the Company has pursued the development of its Cognition Modulation technology
independently. The Company, however, does not anticipate funding clinical trials
relating to this program in the absence of a strategic partner. No assurances
can be given that the Company will be able to identify a strategic partner, or
that in the event the Company identifies a strategic partner, that such
strategic partner will enter into an alliance with the Company or that the
operation of any such alliance will be successful.

  ALZHEIMER'S DISEASE

         Role of Glial Cells in Alzheimer's Disease. The cause of Alzheimer's
Disease is unknown, and there are no proven means of prevention or cure. The
Company believes that research in Alzheimer's Disease has been directed
primarily at providing replacement therapy for neurotransmitter deficiencies,
such as in the cholinergic system, in order to alleviate the symptoms. Attempts
to stop the progression of the disease have centered on identifying a
neurotrophic factor, or combination of factors, which may slow neural
degeneration. The Company believes that glial cells have received inadequate
attention in the study of Alzheimer's Disease. Glial cells are one of the two
interrelated networks of cells in the nervous system. The interrelated networks
of cells consists of neurons, which transfer and process information from around
the body, and glial cells, which monitor and regulate the neuronal system and
play an active role in maintaining normal brain function. Recent research into
Alzheimer's Disease has focused on the role of beta-amyloid in the formation of
senile neuritic plaques.

  The Company's Alzheimer's Disease Program

         Utilizing its strengths in glial cell technology, the Company is
conducting research to develop therapeutic products to slow the progression of
Alzheimer's Disease. In October 1994, the Company and Janssen entered into the
Janssen Agreement to collaborate on the discovery and development of compounds
suitable for the treatment of Alzheimer's Disease and other neurodegenerative
diseases. The Company is primarily pursuing two specific mechanisms by which
glial cells seem to play a role in the amyloid-associated neurotoxicity of
Alzheimer's Disease.

         Beta-Amyloid Induced Inflammation. The Company has discovered that
beta-amyloid peptide, the major component of senile plaques, causes significant
changes in glial cell metabolism. The action of beta-amyloid on microglia leads
to the release of inflammatory cytokines such as interleukins and tumor necrosis
factor. A similar release of cytokines has been reported to occur in the brain
of Alzheimer's patients. The Company is working with Janssen on the development
of small molecular weight compounds that reduce the effects of beta-amyloid

                                       -4-

<PAGE>   7



on glial cells and thus block or reduce the release of inflammatory agents. A
number of high capacity assay systems have been developed by the Company which
are being used to analyze Janssen's pharmaceutical library for molecules which
inhibit these beta-amyloid-induced actions. As a result of this analysis,
several potential lead compounds have been identified.

         Inhibitors of Complement Activation. The Company is also pursuing
research relating to activated proteins from the classical complement cascade
that are associated with beta-amyloid in Alzheimer's Disease senile plaques. The
complement cascade is part of the immune response typically invoked in response
to systemic infections, resulting in the death of pathogenic cells, but is not
usually found in the brain. The Company has discovered that beta-amyloid can
bind one of these factors and activate the complement cascade, providing an
explanation for the presence of activated complement in patients with
Alzheimer's Disease. The Company is working with Janssen on the development of
small molecular weight compounds that would block this complement activation.
The Company has developed proprietary screens and has used these to identify
several potential lead compounds that block beta-amyloid induced activation of
the complement cascade.

         Alzheimer's Disease Models. The Company has also developed secondary
screens with which to further characterize compounds identified in the
high-throughput screens. In addition, Janssen is funding the development of an
animal model of Alzheimer's Disease. To date, Company scientists have
demonstrated that the deposition of fibrillar beta-amyloid results in activation
of neuroglia in this model. Moreover, certain aspects of the inflammatory
response seen in Alzheimer's Disease seem to occur in this model. If the
appropriate aspects of Alzheimer's Disease pathology are replicated in this
model, it will be used to test the in vivo efficacy of selected compounds.

  The Janssen Agreement

         Under the terms of the Janssen Agreement, Johnson & Johnson Development
Corporation, a subsidiary of Johnson & Johnson, made an equity investment in the
Company. Janssen, a wholly owned subsidiary of Johnson & Johnson, paid the
Company an initial licensing fee. The Janssen Agreement provides funding by
Janssen to the Company for Alzheimer's Disease research through October 1997.
The Janssen Agreement is renewable, at Janssen's options, for one or two years
thereafter. In addition, in September 1995, the Company entered into an addendum
to the Janssen Agreement in order to expand the scope of the collaboration on
Alzheimer's Disease to include research relating to inhibitors of complement
activation. Janssen is required to make additional payments to the Company upon
the attainment of certain clinical and developmental milestones. Janssen is also
responsible for all development costs, including the cost associated with
clinical trials and obtaining regulatory approval. Janssen's parent, Johnson &
Johnson, has worldwide distribution rights for any products developed as a
result of this collaboration. The Company will receive a royalty from Janssen on
any sales of such products.

  COGNITION MODULATION

         The Company is developing a class of small molecular weight compounds
designed to act on the histamine H3 receptor in the brain. Histamine is a
chemical messenger, released from certain neurons in the brain, which regulates
sleep/wake states and modulates levels of arousal and alertness in the conscious
state. The histamine H3 receptor is predominately found in the brain and
regulates the synthesis and release of histamine in the brain. An antagonist to
this receptor would lead to enhanced states of arousal and alertness. The
histamine H3 receptor antagonists may be useful in treating several disorders in
which general central nervous system arousal is desirable. An agonist to the
receptor may prove useful for treating disorders such as anxiety and insomnia.
To date, the Company has funded its Cognition Modulation program independently
of strategic partners and retains all of the worldwide commercial rights to any
products it develops. The Company, however, does not anticipate completing
clinical trials relating to its Cognition Modulation program without the
collaboration of a strategic partner. There can be no assurance that the Company
will be able to enter into an agreement with such a strategic partner for its
Cognition Modulation program on acceptable terms, if at all.

         H3 Receptor Antagonists. The Company believes histamine H3 receptor
antagonists could provide a therapeutic approach for enhancing cognition and
positive behavior in patients with disorders characterized by

                                       -5-

<PAGE>   8



memory and learning deficiencies. Such an agent could also be useful in arousing
patients with various forms of depression of the central nervous system such as
narcolepsy. The Company has discovered and developed a selective histamine H3
receptor antagonist, which has been shown in in vivo studies to be available to
the brain after oral administration and to selectively block the histamine H3
receptor in the brain. In preclinical studies, the histamine H3 antagonist
improves learning and memory and has potential advantages in both safety and
abuse potential and has a prolonged duration of action.

         The Company has also developed and synthesized a chemical library of
more potent second generation H3 antagonist candidates. These second generation
histamine H3 receptor antagonists demonstrate improved in vitro receptor
selectivity profiles and enhanced potency. In preclinical models, these
candidates have also been shown to enter the brain and enhance histamine release
and are being tested for efficacy.

         While there are currently available products for the treatment of the
conditions mentioned above, the Company is not aware of any such products based
on the histamine H3 receptor antagonists. The Company has received allowances of
certain U.S. patent applications that cover the compounds and use thereof. The
Company filed U.S. and PCT patent applications covering its second generation
histamine H3 receptor antagonists. The Company has received allowances for a
U.S. patent covering composition of matter for one series of the second
generation H3 antagonists.

         H3 Receptor Agonists. The Company has also begun research on developing
a histamine H3 receptor agonist to reduce levels of wakefulness and arousal for
use in the treatment of anxiety and insomnia. It has developed several compounds
to date which have high affinity for the histamine H3 receptor and in animal
models have been shown to penetrate the blood brain barrier and occupy histamine
H3 receptors. The Company continues to synthesize and screen new compounds as
potential selective agonists at the histamine H3 receptor.

COMPETITION

         The Company competes with both small biotechnology and established
pharmaceutical companies in all of its product development programs.
Furthermore, academic institutions, governmental agencies, and other public and
private research organizations also continue to conduct research, seek patent
protection, and establish collaborative arrangements with commercial entities
for product development and marketing. Products resulting from these activities
may compete directly with any products developed by the Company. These companies
and institutions also compete with the Company in recruiting and retaining
highly qualified scientific personnel.

         Although the Company is not aware of any products on the market that
would directly compete with ADCON-L or ADCON-T/N, there are products which would
compete with another member of the ADCON family of products. One product,
Interceed(TM), has been marketed for several years by Johnson & Johnson to
prevent surgical adhesions following pelvic surgeries. Genzyme Corporation is
developing products to inhibit surgical adhesions following both pelvic and
abdominal surgeries and has received FDA approval for its Seprafilm(TM) product
for use in pelvic and abdominal surgeries. In addition, Lifecore Biomedical,
Inc. is conducting pivotal clinical studies for its surgical adhesion prevention
product, LUBRICOAT(TM), a hyaluronate- based gel for use in the gynecological
setting. There are significant efforts by others, including many large
pharmaceutical companies and academic institutions, to develop therapeutic
products which may compete with the products that are being developed by the
Company relating to its Alzheimer's Disease and Cognition Modulation programs.
Some of these products may be at a more advanced stage of development than the
Company's products. In addition, there may be substantial competition in the
biopharmaceutical and medical industries, both from specialized firms and from
major pharmaceutical, chemical, medical device and surgical supply companies.
Many of the Company's potential competitors have product development
capabilities and financial and human resources greater than the Company, and
have manufacturing, marketing, sales and distribution capabilities that the
Company does not have. Universities and other research institutions may develop
similar technologies and processes which, in some instances, may be utilized by
others to compete with the Company's products.

         The Company expects to encounter significant competition for each of
its product candidates. To compete successfully the Company will be required to
develop and maintain scientifically advanced technology,

                                       -6-

<PAGE>   9



develop proprietary products, attract and retain highly qualified personnel,
obtain patent or other protection for its products, obtain required regulatory
approvals and manufacture and successfully market its products, either alone or
through collaboration with third parties.

         UNCERTAINTY OF HEALTH CARE REIMBURSEMENT. The Company's ability to
successfully commercialize its products will depend in part on the extent to
which reimbursement for the costs of such products and related treatments will
be available from government health administration authorities, private health
coverage insurers and other organizations. In addition, in both the U.S. and
elsewhere, sales of health care products are dependent on the availability of
reimbursement to the consumer from third-party payers, such as government and
private insurance plans. Significant uncertainty exists as to the reimbursement
status of newly approved health care products, and third-party payers are
increasingly challenging the prices charged for medical products and services.
There can be no assurance that ADCON products will be considered cost effective
and that reimbursement will be available or will be sufficient to allow the
Company to sell its products on a competitive basis. The Company's business may
be materially adversely affected by the continuing efforts of governmental and
third-party payers to contain or reduce the costs of health care through various
means. For example, in certain foreign markets the pricing or profitability of
health care products is subject to government control. In the U.S., there have
been, and the Company expects that there will continue to be, a number of
federal and state proposals to implement similar government control. While the
Company cannot predict whether any legislative or regulatory proposals or
reforms will be adopted, such proposals or reforms could have a material adverse
effect on the Company. If adequate coverage and reimbursement levels are not
provided by government and third-party payers for uses of the Company's
products, the market acceptance of these products could be adversely affected.

RESEARCH AND DEVELOPMENT

         The Company is in the early stage of development of certain ADCON
products to complement ADCON-L and ADCON-T/N. The Company is also focusing on
the development of therapeutic products for use in the treatment of certain
nervous system disorders. Although several of these candidate therapeutic
products are in preclinical evaluation, the products currently under development
will require additional research and development, including preclinical and
extensive clinical testing, prior to making application with regulatory
authorities for commercial use. During fiscal 1996, the Company spent
approximately $6.1 million on research and development efforts. There can be no
assurance that the Company's research and development efforts will be successful
or that any candidate products will prove to be safe and effective in clinical
trials and receive necessary regulatory approvals.

GOVERNMENT REGULATION

         U.S. Regulation. The manufacture and sale of the Company's products are
subject to regulation by numerous authorities, principally the FDA, and
corresponding state and foreign authorities. The regulatory process is lengthy,
expensive and uncertain. Prior to commercial sale in the United States, most
medical devices and new drugs, including the Company's products under
development, must be cleared or approved by the FDA. In addition, certain
material changes or modifications to medical devices and drugs are also subject
to FDA review and approval. Securing FDA clearances and approvals may require
the submission of extensive clinical data and supporting information to the FDA.
Product clearances and approvals can be withdrawn for failure to comply with
regulatory requirements or upon the occurrence of unforeseen problems following
initial marketing. The FDA and other agency requirements for manufacturing,
product testing and marketing also can vary depending on whether the product is
a medical device or new drug. There can be no assurance that the Company will be
able to obtain necessary regulatory clearances or approvals on a timely basis,
if at all, for any of its products under development, and delays in receipt or
failure to receive such clearances or approvals, the loss of previously received
clearances or approvals, or failure to comply with existing or future regulatory
requirements could have a material adverse effect on the Company's business,
financial condition and results of operations. Moreover, regulatory clearances
or approvals for products such as medical devices and new drugs, even if
granted, may include significant limitations on the uses for which such products
may be marketed. Additionally, product clearances or approvals can be withdrawn
for failure to comply with regulatory requirements. In addition, certain
material changes to medical devices and drugs also are subject to FDA review

                                       -7-

<PAGE>   10



and approval. There can be no assurance that any clearances or approvals that
are required, once obtained will not be withdrawn or that compliance with other
regulatory requirements can be maintained.

         Manufacturers of medical devices and drugs also are required to adhere
to the FDA regulations setting forth requirements for GMP regulations and
similar requirements, in other countries, which include requirements relating to
product testing and quality assurance as well as the corresponding maintenance
of records and documentation. Failure to comply with applicable GMP or other
applicable regulatory standards, such as International Standard Organization's
("ISO"), could result in sanctions being imposed on the Company or the
manufacture of its products, including warning letters, fines, injunctions,
civil penalties, failure of the FDA or other regulatory authorities to grant
premarket clearance or premarket approval of medical devices and drugs,
operating restrictions and criminal prosecution. There can be no assurance that
the current manufacturer of the Company's products will comply with all
applicable regulatory requirements or that the Company would be able to identify
a new or additional manufacturers for its products on terms acceptable to the
Company. Since the Company's products are in research or development phases in
the United States, the Company cannot accurately predict all relevant regulatory
requirements or related issues. Changes in existing laws, regulations or
policies and the adoption of new laws, regulations or policies could prevent the
Company from, or could affect the timing of, achieving compliance with
regulatory requirements, including current and future regulatory clearances or
approvals, where necessary.

         Other Regulation. The advertising of most of the FDA-regulated products
will be subject to Federal Trade Commission jurisdiction. The Company also is
subject to regulations by the Occupational Safety and Health Administration and
by the U.S. Environmental Protection Agency under such statutes as the Toxic
Substances Control Act, the Resource Conservation and Recovery Act and other
laws. Various states and other foreign governments often have comparable health
and environmental laws.

         Foreign Regulation. The Company is subject in many countries to
regulatory requirements concerning drugs and medical devices and relating to
human clinical trials, marketing approvals and product testing.

         From January 1, 1995, the European Union has implemented the Medical
Devices Directive (MDD). This new legislation includes, among others,
requirements with respect to the design, safety, performance and manufacture of
products. Under the system established by the MDD, all medical devices other
than active implants and in vitro diagnostic products must quality for CE
Marking by June 14, 1998. During the transitional period (from January 1, 1995
to June 14, 1998) medical devices can be placed on the market and put into
service if they comply with the requirements of the MDD or national requirements
that were in force on December 31, 1994.

         In order to qualify for CE Marking, the manufacturer must comply with
the Essential Requirements of the MDD. These relate to safety and performance.
In order to demonstrate compliance with these requirements of the MDD, the
manufacturer must undergo conformity assessment which depends on the class of
the product. The Company has chosen as its conformity assessment type testing of
the product by a Notified Body and assessment of the manufacturer's quality
system used in production by a Notified Body. The Notified Body chosen by the
Company is a Dutch non-governmental entity which, after an accreditation
proceeding, has been notified by the Dutch Competent Authority to the European
Commission that it may carry out conformity assessment tasks under the MDD. Once
all the necessary conformity assessment tasks have been completed to the
satisfaction of the Notified Body and the manufacturer is convinced that it is
in full compliance with the MDD, CE Marking may be affixed on the products
concerned.

         Although member countries must accept for marketing medical devices
bearing a CE Marking without imposing further requirements related to product
safety and performance, each country may require the use of its own language on
labels and instructions for use. National Competent Authorities who are required
to enforce compliance with the requirements of the MDD, can restrict, prohibit
and recall CE marked products if they are unsafe. Such a decision must be
confirmed by the European Commission in order to be valid. Member countries can
impose additional requirements as long as they do not violate the MDD or
constitute technical barriers to trade.


                                       -8-

<PAGE>   11



         Within the European Union, premarket compliance for devices must be
supported by clinical data of a type and extent set out by European Union
directives, standards as interpreted by Competent Authorities and Notified
Bodies. The approval process for the commencement of clinical trials varies
currently from country to country. To the extent possible, the Company conducted
clinical trials are designed to develop a regulatory package sufficient for
multi-country European Union approval, without the need to duplicate clinical
trials for individual country approvals.

         The new post-1994 regimes for medical devices are based on directives.
Devices will be subject to, in addition to other future European Union or other
countries legislation, continued national regulation on pricing and
reimbursement, which may vary from country to country. Certain other
requirements such as clinical investigations and post marketing surveillance,
will probably be subject to significant variation among countries.

PATENTS, TRADEMARKS AND TRADE SECRETS

         Proprietary protection for the Company's product candidates, processes,
and know-how is important to the Company's business. The Company's policy is to
file patent applications to protect technology, inventions and improvements
that are considered important to the development of its business. The Company
also relies upon trade secrets, know-how and continuing technological
innovation to develop and maintain its competitive position. The Company intends
to aggressively prosecute and defend its patents and proprietary technology.

         The Company has filed U.S. and corresponding foreign patent
applications relating to its product candidates in the ADCON family. These
applications cover various methods of use and pharmaceutical compositions. U.S.
Patent No. 5,605,938 issued on February 25, 1997. This patent has claims
covering ADCON products and methods for inhibiting fibrosis. The Company is also
pursuing broader and additional claims in various applications that cover
methods of the use of related products and their pharmaceutical compositions.
Two of these applications have been allowed. The Company is not aware that its
manufacture, use and/or sale of its ADCON products infringes any valid claim of
any issued patents. There can be no assurance, however, that infringement of
such claims will not be found to exist. See "Business -- ADCON Research and
License Agreements" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

         The Company has received allowances for two U.S. patent applications
that are licensed to the Company from the University of Toledo. These allowed
applications relate to a first series of synthetic compounds that are histamine
H3 receptor antagonists, to methods of use and to pharmaceutical compositions
comprising these compounds. A U.S. patent licensed to the Company from the
University of Toledo has also issued that covers processes for the manufacture
of intermediates for certain of the compounds. In addition, the Company jointly
owns a U.S. Patent with the University of Toledo that relates to the use of the
first series of synthetic compounds as appetite suppressants.

         Three further U.S. patent applications filed solely by the Company and
certain corresponding foreign applications, covering two different series of
synthetic H3 receptor antagonist compounds, and one series of H3 receptor
agonist compounds, their methods of medical use and pharmaceutical compositions,
are pending. A U.S. patent application covering one series of synthetic H3
receptor antagonist compounds has been allowed for claims of composition of
matter. No assurance can be given that any claims relating to these products and
methods will be issued.

        A U.S. patent has been issued to Institut National de la Sante et de la
Recherche Medicale ("INSERM"), Societe Civile Bioprojet, and Universite de Caen
(the "INSERM patent") covering certain histamine H3, receptor antagonists
including some of the compounds in one of the Company's allowed U.S. patent
applications licensed from the University of Toledo. The INSERM patent has an
earlier effective filing date than that of the Company's histamine H3,
receptor antagonist application relating to this series of compounds. However,
the Company believes the its date of invention for the pertinent compounds may
be earlier that the date of invention to which the INSERM application is
entitled in the U.S. for purposes of an interference proceeding. However,
should such an interference proceeding be declared prior to issuance of the
Company's application, there can be no assurance that the Company would
prevail. If the Company's allowed patent application, which may claim some of
the same subject matter as the INSERM patent, issues as expected, either patent
owner can bring a civil action to determine the validity of the potentially
interfering patents. There can be no assurance that such an action will not be
instituted, and if instituted, there can be no assurance that the Company
would prevail.

                                       -9-

<PAGE>   12

         The Company is prosecuting its patent applications with the U.S. Patent
and Trademark Office and with various foreign patent offices but the Company
does not know whether any of its applications will result in the issuance of any
patents or, if any patents are issued, whether any issued patent will provide
significant proprietary protection or will be circumvented or invalidated.
During the course of patent prosecution, patent applications are evaluated,
inter alia, for utility, novelty, nonobviousness and enablement. The U.S. Patent
and Trademark Office may require that the claims of an initially filed patent
application be amended if it is determined that the scope of the claims includes
subject matter that is not useful, novel, nonobvious or enabled. Furthermore, in
certain instances, the practice of a patentable invention may require a license
from the holder of dominant patent rights. In cases where one party believes
that it has a claim to an invention covered by a patent application or patent of
a second party, the first party may provoke an interference proceeding in the
U.S. Patent and Trademark Office or such a proceeding may otherwise be declared
by the Patent and Trademark Office. In general, in an interference proceeding,
the Patent and Trademark Office would review the competing patents and/or patent
applications to determine the validity of the competing claims, including but
not limited to determining priority of invention. Any such determination would
be subject to appeal in the appropriate U.S.
federal courts.

         There can be no assurance that additional patents will be obtained by
the Company or that issued patents will provide a substantial protection or be
of commercial benefit to the Company. The issuance of a patent is not conclusive
as to its validity or enforceability, nor does it provide the patent holder with
freedom to operate without infringing the patent rights of others. A patent
could be challenged by litigation and, if the outcome of such litigation were
adverse to the patent holder, competitors could be free to use the subject
matter covered by the patent, or the patent holder may license the technology to
others in settlement of such litigation. The invalidation of key patents owned
by or licensed to the Company or non-approval of pending patent applications
could create increased competition, with potential adverse effects on the
Company and its business prospects. In addition, there can be no assurance that
any applications of the Company's technology will not infringe patents or
proprietary rights of others or that licenses that might be required as a result
of such infringement for the Company's processes or products would be available
on commercially reasonable terms, if at all.

         The Company cannot predict whether its or its competitors' patent
applications will result in valid patents being issued. Litigation, which could
result in substantial cost to the Company, may also be necessary to enforce the
Company's patent and proprietary rights and/or to determine the scope and
validity of others' proprietary rights. The Company may participate in
interference proceedings that may in the future be declared by the U.S. Patent
and Trademark Office to determine priority of invention, which could result in
substantial cost to the Company. There can be no assurance that the outcome of
any such litigation or interference proceedings will be favorable to the Company
or that the Company will be able to obtain licenses to technology that it may
require or that, if obtainable, such technology can be licensed at a reasonable
cost.

         The patent position of biotechnology and biopharmaceutical firms
generally is highly uncertain and involves complex legal and factual questions.
To date, no consistent policy has emerged regarding the breadth

                                      -10-

<PAGE>   13



of claims allowed in biotechnology and biopharmaceutical patents. Accordingly,
there can be no assurance that patent applications owned or licensed by the
Company will result in patents being issued or that, if issued, the patents will
afford protection against competitors with similar technology.

         The Company also attempts to protect its proprietary compounds,
products and processes by relying on trade secret laws, and on non-disclosure
and confidentiality agreements. The Company requires its employees, consultants,
members of the Scientific Advisory Board, outside scientific collaborators and
sponsored researchers, and other advisors to execute confidentiality agreements
upon the commencement of employment or consulting relationships with the
Company. These agreements generally provide that all confidential information
developed or made known to the individual during the course of the relationships
is to be kept confidential and not disclosed to third parties except in specific
circumstances. In the case of employees, the agreements provide that any
inventions conceived by the individual within the scope of his employment shall
be the exclusive property of the Company. There can be no assurance, however,
that these agreements will provide meaningful protection for any of the
Company's trade secrets in the event of unauthorized use or disclosure of such
information.

EMPLOYEES

         As of December 31, 1996, the Company had 52 full-time employees. Of the
52 full-time employees, 36 are engaged in, or directly support, research and
development.

ITEM 2.  PROPERTIES.

         The Company's personnel conduct the Company's internal research at a
35,705 square foot leased facility in Beachwood, Ohio, a suburb of Cleveland.
The leases for 11,569, 9,140, 13,000 and 1,996 square feet of space in this
facility expire on December 31, 1998, December 31, 2001, December 31, 2001 and

to this note or on Bank's loan account records) in lawful money of the United
States, together with interest payable commencing on ___________________, 1996, 
and Monthly thereafter and on demand. Prior to demand, principal and any overdue
interest shall bear interest computed daily (on the basis of a 360-day year and
actual days elapsed) at a fluctuating rate which is zero percent (0%) per annum
above the Prime Rate.

_______________  Debtor is not permitted to obtain advances other than the
   Initials      initial amount borrowed hereunder.

                  This note represents an arrangement that allows Debtor to
                  obtain advances without giving Bank a separate note for each
                  advance. However, THIS NOTE DOES NOT OF ITSELF CONSTITUTE A
                  COMMITMENT BY BANK TO MAKE ANY ADVANCES TO DEBTOR. Bank will

   Initials       that each advance so recorded shall be prima facie evidence 
                  that an advance was made on the date and in the amount
                  indicated. The number of advances and the amount of each
                  advance are not limited; provided, however, that the maximum

therefor, whichever is applicable, Debtor, in each case, will incur and shall

(5%) of the unpaid amount. The payment of a late charge will not impair any
holder's right to demand repayment of this note.

but unpaid interest and fees, in that order, on an invoice by invoice basis in
the order of their respective due dates, until paid in full, then to late
charges and then to principal.

such other address that Debtor may furnish in writing to an appropriate officer
of Bank and shall be mailed not less than fifteen (15) days prior to the
effective date of such change.

          Distributor agrees to indemnify, defend and hold Gliatech free and

          following the expiration of the notice period) or upon termination of
          this Agreement if effected without advance notice, the right of

          Payment shall be made within thirty (30) days of delivery of such
          inventory to Gliatech.

18.       WARRANTY AND REPRESENTATIONS:

          (a) Gliatech hereby expressly warrants and represents to Distributor
          that all Products purchased by Distributor pursuant to this Agreement
          have been approved for sale and use in the Territory and shall be free
          from defects in materials and workmanship. Gliatech agrees to
          indemnify, defend and hold Distributor harmless against all claims,
          actions, suits, losses, damages and expenses in respect of claims made
          by third parties alleging personal injury or death resulting from use
          of the Product; PROVIDED, HOWEVER, that Gliatech shall not be liable
          to Distributor for any claim by Distributor for loss of profits, or
          for special, incidental or consequential damages owing to any defect
          in the Products, whether caused by Gliatech's negligence or otherwise.
          Notwithstanding anything to the contrary herein, Gliatech shall not
          indemnify or defend Distributor or hold Distributor harmless against
          any claim, action, suit, loss, damages or expenses in respect of
          claims arising out of any wrongful act, by Distributor, including any
          breach of this Agreement.

          (b) As between Gliatech and Distributor, the liability of Gliatech to
          Distributor, otherwise than in respect of third party claims, shall be
          limited at Gliatech's option to replace those Products which are shown
          to be defective either in materials or workmanship or to issue a
          credit note for the full invoice value of such defective Products.

          (c) Any claim or defect in materials or workmanship shall be allowed
          only when submitted to Gliatech in writing within seven (7) days after
          discovery of the defect, and in no event later than thirty (30) days
          after the delivery of the Products to Distributor, together with the
          alleged defective Products if requested by Gliatech. No claim shall be
          allowed in respect of any Products which have been altered, neglected,
          damaged, handled or stored in any manner which adversely affects them.

          (d) Except for the warranties and representations stated above,
          Gliatech makes no warranties or representations of any kind
          whatsoever, express or implied, and all other warranties and
          representations of whatever kind, including warranties of
          merchantability and fitness for a particular purpose, are hereby
          disclaimed by Gliatech and waived by Distributor. The preceding
          subclauses (a) through (c) of this Article 19 set forth exclusively
          all of Gliatech's liability in contract, tort or otherwise in the
          event of defective Products and/or for breach of any warranties or
          representations.

          (e) Distributor agrees to indemnify, defend and hold Gliatech free and
          harmless against all claims, actions, suits, losses, damages, expenses
          and other liabilities of every kind and

                                      X-14

          nature asserted or sustained by third parties by reason of any act of
          neglect or breach committed by Distributor or any of its employees,
          agents or representatives.

          (f) Gliatech represents that so long as Distributor uses reasonable
          commercial efforts to control its inventories and rotates its stock of
          Products, Gliatech shall use its reasonable commercial efforts to
          promptly replace any expired Products which it accepts for return.
          Returned Products will be accepted by Gliatech if: (1) the Products
          are received by Gliatech's Director of Manufacturing in Cleveland,
          Ohio, USA, after the date of expiration marked on the package, (2) the
          Products are in saleable condition and the original packaging is
          inspected by Gliatech and found to be intact and (3) an acceptance
          notice has been issued by Gliatech. Accepted returns will be replaced
          by Gliatech free of any purchase, shipping or duties to Distributor.

          to be illegal, invalid or unenforceable in any jurisdiction shall be
          ineffective in such jurisdiction to the extent of such illegality,
          invalidity or unenforceability, without affecting, impairing or
          invalidating the remaining provisions of this Agreement in any

Gliatech Inc. and Subsidiaries (A Development Stage Enterprise)

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

OVERVIEW

Since commencing operations in 1988, the Company has been a development stage
company. The Company is developing and commercializing the ADCON(R) family of
products to inhibit excessive scarring and adhesions after surgery. Based on
European pivotal clinical studies and other compliance efforts and submission of
data, the Company obtained regulatory clearance to affix CE Marking on
ADCON(R)-L and ADCON(R)-T/N, thereby allowing ADCON(R)-L and ADCON(R)-T/N to be
marketed in the 15 European Union countries for lumbar disc surgery and tendon
and peripheral nerve surgeries, respectively. The Company has entered into
distribution agreements with independent distributors for ADCON(R)-L and
ADCON(R)-T/N in Australia, Austria, Belgium, Germany, Italy, The Netherlands,
New Zealand, Scandinavia, Spain, Switzerland and the United Kingdom. In
addition, the Company is pursuing the development of drug candidates for the
treatment of certain nervous system disorders, including Alzheimer's Disease.
Since inception, the Company's revenues have been derived primarily from
contract research payments from a research contract with Janssen Pharmaceutica,
N.V. of Belgium ("Janssen"), a wholly-owned subsidiary of Johnson & Johnson, to
collaborate on the discovery and development of compounds to slow the
progression of Alzheimer's Disease (the "Janssen Agreement"). The Company has
also received revenues from various government grants which have been awarded to
the Company.

RESULTS OF OPERATIONS

Years ended December 31, 1996, 1995 and 1994

REVENUES

Total revenues increased to $3,877,975 in 1996 from $2,653,606 in 1995 and
$1,144,934 in 1994. The Company had research revenues in 1996 of $2,854,860 from
its research contract with Janssen compared to research revenues of $2,216,668
and $917,691 in 1995 and 1994, respectively. The Janssen collaboration began in
October 1994 and, in 1994, research revenues included a $500,000 one-time
up-front licensing fee. The increase in 1995 research revenues is a result of
recognizing a full year of the Janssen research contract revenues in 1995. In
September 1995, the Company entered into an addendum to the Janssen Agreement in
order to expand the scope of the collaboration with Janssen on Alzheimer's
Disease to include research relating to inhibitors of complement activation.
This addendum to the Janssen Agreement added approximately $875,000 to research
contract revenues in 1996 and $290,000 to research contract revenues in 1995.

     The Company's product sales increased to $900,932 in 1996 from $182,233 in
1995 and $86,340 in 1994. The increase in product sales in 1996 resulted from
sales of the Company's ADCON(R)-L and ADCON(R)-T/N products in certain European
countries, as well as Australia and New Zealand. The increase in product sales
in 1995 was due to initial inventory stocking orders for several new European
distributors after the Company obtained regulatory approval of ADCON(R)-L in
1995.

     The Company's government-funded research grant revenues were $122,183 in
1996, $254,705 in 1995 and $140,903 in 1994. The levels of grant revenues were a
direct result of the number of government-funded research grants awarded the
Company in each year.

EXPENSES

Expenses for research and development increased to $6,119,533 in 1996 from
$5,107,154 in 1995 and $4,599,834 in 1994. The increases in 1996 and 1995 were
due primarily to increased staffing and clinical contract expenses due to of the
initiation of pivotal clinical trials in the U.S. for both ADCON(R)-L and
ADCON(R)-T/N beginning in the fourth quarter of 1995 and continuing throughout
1996. Additionally, the increase in 1996 is a result of additions in staffing
and purchases of laboratory supplies and services relating to increased research
activities beginning in the first quarter of 1996 with respect to Alzheimer's
Disease and Cognition Modulation programs and write-offs of costs associated
with patents which were abandoned due to changes in the technology pursuits of
the Company. Increased expenses associated with the Gliatech's Alzheimer's
Disease program are funded under the Company's agreement with Janssen.

     Selling, general and administrative expenses were $4,070,173 in 1996,
$2,599,290 in 1995 and $2,365,395 in 1994. The increase for each of these
periods was primarily due to an increase in sales and marketing expenses as
Gliatech continued to expand its sales and marketing efforts for its ADCON(R)-L
and ADCON(R)-T/N products in the European Union and

10

Australia and New Zealand. Additionally, Gliatech incurred increased general
and administrative expenses of $230,000 in 1996 associated with the filing of a
registration statement with the U.S. Securities and Exchange Commission (SEC)
for an offering of Common Stock which was subsequently withdrawn due to
unfavorable market conditions. The Company also incurred increased general and
administrative expenses in 1996 associated with its first full year of
reporting as a publicly traded company.

     Depreciation and amortization expense was $166,411 in 1996, $170,395 in
1995 and $272,221 in 1994. This expense has decreased over the three-year period
as several Company assets have become fully depreciated.

     Cost of products sold increased to $341,534 in 1996 from $122,589 in 1995
and $57,848 in 1994. These increases in cost of products sold were due primarily
to the increases in products sales for the corresponding three year period.
However, cost of products sold decreased as a percentage of product sales in
1996 to 38 percent from 67 percent in 1995 and in 1994. This decrease was
primarily due to improved absorption of manufacturing overhead costs as a result
of increased production volumes in 1996. In all three periods, cost of products
sold included costs associated with the start-up of manufacturing processes with
an outside contract manufacturer for ADCON(R)-L and ADCON(R)-T/N.

INTEREST INCOME

Net interest income increased to $1,120,121 in 1996 from $359,961 in 1995 and
$97,794 in 1994. The increases in 1996 and 1995 were due primarily to the
interest earned on the cash received in the October 1995 initial public offering
of Common Stock and the June 1995 private placement of equity securities.

INCOME TAXES

At December 31, 1996, the Company had net operating tax loss carryforwards of
approximately $14,819,000 for income tax purposes. In addition, at December 31,
1996, the Company had approximately $1,883,000 of research and development tax
credit carryforwards. Such losses and credit carryforwards may be carried
forward to reduce future tax liabilities and expire at various dates between
2003 and 2011. The Company has offset the tax benefit of the net operating loss
and tax credit carryforwards with a valuation allowance as realization of the
benefit is not assured. Pursuant to the Tax Reform Act of 1986, the utilization
of net operating loss and research and development tax credit carryforwards for
tax purposes may be subject to an annual limitation if a cumulative change in
ownership of more than 50% occurs over a three-year period. The future issuance
of securities by the Company and/or sales of securities by the Company's
principal stockholders could result in such a change of ownership.

LIQUIDITY AND CAPITAL RESOURCES

The Company received net proceeds, after expenses of the offering, of
approximately $19,647,000 from its initial public offering in which the Company
sold 2,300,000 shares of Common Stock at an initial public offering price of
$9.50 per share in October 1995. Prior to the public offering, the Company had
financed its operations primarily through the private placement of its equity
securities and to a lesser extent through federally sponsored research grants
and research contract and licensing fees. In June 1995, the Company received net
proceeds of approximately $4,653,000 through a private placement of equity
securities. Since its inception, the Company has received $49,293,835 in net
proceeds from equity financings. In addition, from its inception through
December 31, 1996, the Company has recognized revenue of $5,989,219 from its
research collaboration agreement with Janssen, $1,090,382 from several federally
sponsored research grants and $1,169,505 from product sales. Janssen is expected
to pay the Company approximately $2,800,000 during fiscal 1997. The Company also
has established a $1,500,000 unsecured line of credit with a bank. As of
December 31, 1996, the Company had no borrowings against the line of credit.

     In order to preserve principal and maintain liquidity, the Company's funds
are invested in commercial paper and other short-term investments. As of
December 31, 1996 and December 31, 1995, the Company's cash and cash equivalents
and short-term investments totaled $17,995,769 and $23,023,301, respectively.

     Also, during 1995, the Company received two $100,000 Phase I Small Business
Innovation Research (SBIR) grants from the National Institute of Neurological
Disorders and Stroke (NINDS) division of the National

                                                                              11

Institute of Health (NIH) to develop histamine H(3) receptor agents. In
early 1997, the Company was awarded a Phase II SBIR Program grant from the
NINDS for research evaluating histamine H(3) receptor antagonists to treat
Attention Deficit Hyperactive Disorders. The grant has a two-year term and will
provide as much as $750,000 in funding. If the Company is successful in other
Phase I research, additional Phase II awards could be sought for funding to aid
in further development of these agents; however, there is no assurance that
such additional funding will be obtained.

     The Company anticipates that a substantial portion of the remaining
proceeds of its initial public offering will be used to fund clinical trials of
ADCON(R)-L and ADCON(R)-T/N in the U.S. and the marketing efforts for sales of
the ADCON(R) products. In addition, the Company anticipates that these proceeds
will be used to fund continued development of additional ADCON(R) products, for
the research and development of products relating to its Cognition Modulation
program and for working capital and general corporate purposes. The Company's
future liquidity and capital requirements will depend on many factors,
including, but not limited to, the commercial potential of its ADCON(R) family
of products, the timing of regulatory approvals, the timing and results of
preclinical testing and clinical studies, the progress of the Company's research
and development programs and the ability of the Company to establish and
maintain collaborative arrangements with others for the purpose of funding
certain research and development programs. The Company believes that its current
cash position and other financial resources will enable it to conduct its
current and planned operations through at least fiscal 1998.

     The Company anticipates that it will augment its cash balance through
financing transactions, government grants and further corporate alliances. No
assurances can be given that adequate levels of additional funding can be
obtained on favorable terms, if at all.

     The Company is a party to a license agreement and a related sponsored
research agreement with a university that provides for a royalty of up to 5% of
revenues from products covered by these agreements. In 1995, a dispute regarding
inventorship of the ADCON(R) products and the rights of the university to
receive royalties from sales of ADCON(R) products arose between Gliatech and the
university. The university has threatened litigation regarding this dispute.
There has been no resolution of this matter. The Company is not able to make any
estimate of costs that may arise as a result of any outcomes from this dispute
and there can be no assurance that the Company will not be required to pay any
costs or royalties or that any costs to the Company, or royalties that may
result, from this dispute will not have an adverse effect on the Company.

     Statements regarding the Company's expectations as to demand for its
products, government regulations and certain other information presented in this
Annual Report constitute forward looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Although the Company believes
that its expectations are based on reasonable assumptions within the bounds of
its business and operations, there can be no assurance that actual results will
not differ materially from its expectations. Factors which cause actual results
to differ from expectations include, but are not limited to, uncertainty of
future profitability, uncertainty of market acceptance, adequacy of third party
reimbursement, extent of government regulation, availability of product from
manufacturer, productivity of independent distributors selling ADCON(R) products
in Europe, Australia and New Zealand, continued cooperative efforts by Janssen
in its Alzheimer's Disease collaboration, and uncertainty regarding patents and
proprietary rights.

Gliatech Inc. and Subsidiaries (A Development Stage Enterprise)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years Ended December 31, 1994, 1995 and 1996

A. BACKGROUND AND ACCOUNTING POLICIES

BACKGROUND

Gliatech Inc. (Gliatech) is engaged in the development and commercialization of
medical devices designed to inhibit excess surgical scarring and adhesion
following surgery. In addition, Gliatech is pursuing the development of drug
candidates for the treatment of certain nervous system disorders, including
Alzheimers Disease, and cognitive disorders. Gliatech began operations on August
31, 1988 and is currently in the development stage, as operations consist
primarily of research and development expenditures, and significant revenues
from planned principal operations have not yet been realized. Product sales
consist of sales of Gliatech's first two medical device products, ADCON(R)-L and
ADCON(R)-T/N, to independent distributors in Europe, Australia and New Zealand.

     The consolidated financial statements reflect the financial position and
results of operations of Gliatech Inc. and its wholly-owned subsidiaries (the
Company). Intercompany balances and transactions have been eliminated.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. The carrying amount of the
Company's cash equivalents approximates fair value due to the short-term
maturity of those investments. Cash equivalents are primarily in commercial
paper.

SHORT-TERM INVESTMENTS

The Company's short-term investments, all of which are classified as
available-for-sale, consist primarily of corporate bonds. Such investments are
stated at cost, which approximates fair value due to the short-term maturities
of these securities.

INVENTORIES

Inventories are stated at the lower of cost or market and are valued using the
first-in, first-out method.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Laboratory and office equipment and
leasehold improvements are depreciated on the straight-line basis over the
shorter of the lease period or the estimated useful lives (5 to 10 years).

PATENT RIGHTS AND TRADEMARKS

Patent rights are amortized on the straight-line basis over the shorter of the
estimated useful life of the patented technology or the useful life of the
patent, beginning at the time the patent is granted. Costs associated with
patents that are abandoned are expensed at the date of abandonment. Trademark
costs are amortized on the straight-line basis over the estimated useful life of
the trademark, beginning at the time the trademark is granted.

GOVERNMENT GRANTS

Revenues from government grants are recognized ratably over the period of the
grant.

RESEARCH CONTRACTS AND LICENSING FEE REVENUE

Revenue from the research collaboration agreements are recorded when earned as
defined under the terms of the agreements. Periodic research funding payments
received which are related to future performance are deferred and recognized as
income when earned. Licensing fees and other milestone payments are recognized
as income when earned.

INCOME TAXES

Effective January 1, 1993, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 109, Accounting for Income Taxes. Under SFAS No. 109, the
liability method is used in accounting for income taxes. Under this method,
deferred tax assets and liabilities are determined based on differences between
financial reporting and tax bases of assets and liabilities and are measured
using the currently enacted tax rates and laws that will be in effect when the
differences are expected to reverse. Prior to the adoption of SFAS No. 109,
income tax expense was determined using the deferred method prescribed by
Accounting Principles Board Opinion (APBO) No. 11, Accounting for Income Taxes.

PRO FORMA NET LOSS PER COMMON SHARE

For 1994 and 1995, pro forma net loss per common share is computed using the
weighted average number of shares of common stock outstanding. However, common
and common equivalent shares including preferred stock (all of which converted,
according to their terms, upon the completion of the Company's initial public
offering--see Note G) issued by the Company and stock options and

                                                                              19
<PAGE>   11


warrants granted during the twelve-month period immediately preceding the filing
of the initial public offering at prices below the initial public offering price
have been included in the calculation of the shares used in computing pro forma
net loss per common share as if they were outstanding for all of 1994 and for
the six month period ended June 30, 1995 (the latest interim period reported in
the initial public offering). In addition, common equivalent shares from
preferred stock (all of which converted, according to their terms, upon the
completion of the Company's initial public offering) issued prior to the
twelve-month period immediately preceding the filing of the Company's initial
public offering are included in the computation of pro forma net loss per common
share as if they had been converted on the original date of issuance. Pro forma
net loss per common share for periods subsequent to June 30, 1995 is computed in
accordance with APBO No. 15, Earnings Per Share which does not permit earnings
per share to give effect to anti-dilutive securities. Common equivalent shares
relating to stock options and warrants are excluded for periods subsequent to
June 30, 1995 as their effect is anti-dilutive.

     For 1996, net loss per common share is based on the weighted average number
of common shares. Outstanding common equivalent shares relating to stock options
and warrants are excluded as their effect is anti-dilutive.

STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation in accordance with APBO No.
25, Accounting for Stock Issued to Employees.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

RECLASSIFICATION

Certain amounts in prior years have been reclassified to conform with the 1996
financial statement presentation.

F. INCOME TAXES

At December 31, 1996, the Company has net operating loss carryforwards of
approximately $14.8 million for income tax purposes. In addition, the Company
has approximately $1.9 million in research and development tax credit
carryforwards. Such losses and credit carryforwards are available to reduce
future tax liabilities and expire at various dates between 2003 and 2011. The
Company has offset the tax benefit of the net operating loss and tax credit
carryforwards and other deferred tax assets with a valuation allowance as
realization of the benefits is not assured.

     The Companys net deferred tax assets and liabilities consist of the
following:

     Pursuant to the Tax Reform Act of 1986, the utilization of net operating
loss and research and development tax credit carryforwards for tax purposes may
be subject to an annual limitation if a cumulative change in ownership of more
than 50 percent occurs over a three-year period.

G. CAPITALIZATION

On October 24, 1995, the Company consummated an initial public offering of
2,300,000 shares of common stock at an initial public offering price of $9.50
per share (the "Offering"). The Company received net proceeds from the Offering
of approximately $19,647,000. In connection with the Offering, an amendment to
the Company's Certificate of Incorporation was filed to effect a five-for-one
reverse stock split of each share of common stock. All share and per share
information in the accompanying financial statements and conversion ratios of
all series of Preferred Stock and Class A Common Stock were adjusted to reflect
the reverse split. Immediately prior to the consummation of the Offering, all
shares of Class A Common Stock and all series of Preferred Stock automatically
converted pursuant to the Company's Certificate of Incorporation at applicable
conversion rates into a total of 4,718,014 shares of common stock.

                                                                              21
<PAGE>   13


     After the conversion and immediately prior to the consummation of the
Offering, the Company filed a Restated Certificate of Incorporation which
authorized the issuance of 30,000,000 shares of common stock and 5,000,000
shares of Preferred Stock at $.01 par value.

     At December 31, 1996, 1,166,510 shares of common stock are reserved for
issuance under the stock option plans, 20,000 shares are reserved for issuance
under common stock warrants outstanding for $7.50 per share, and 5,134 shares
are reserved for common stock bonuses declared but unissued at December 31,
1996.

     Prior to April, 1991 certain preferred stock issuances were mandatorily
redeemable, and accordingly, periodic accretion to the redemption price was
charged to the deficit accumulated during the development stage.

H. STOCK OPTION PLANS

The Company has three stock-based compensation plans. The Company applies APBO
No. 25, Accounting for Stock Issued to Employees and related Interpretations in
accounting for its plans, which requires that for certain options granted, the
Company recognize as compensation expense the excess of the deemed fair value
for accounting purposes of the common stock over the exercise price of the
options. For the majority of options, no compensation cost has been recognized.
Had compensation cost for the Company's three stock-based compensation plans
been determined based on the fair value at the grant dates for awards under
those plans consistent with the method of SFAS No.123, Accounting for
Stock-Based Compensation, the Company's net loss and net loss per share would
have increased to the pro forma amounts indicated below:

</TABLE>

     Under the Amended and Restated 1989 Stock Option Plan, the Company is
authorized to issue 1,020,000 incentive stock options. Under the 1992 Directors
Option Plan, the Company is authorized to issue 40,000 non-qualified stock
options. Under the 1995 Non-employee Directors Stock Option Plan, the Company is
authorized to issue 150,000 non-qualified stock options. These options vest over
a three, four or five year period and become exercisable in part one year after
date of grant and expire at the end of ten years.

     For pro forma calculations, the fair value of each option grant is
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted-average assumptions used for grants in 1995 and 1996:
expected volatility of 67 percent, risk-free interest rates ranging from 5.32
percent to 6.49 percent, and an average expected life of 4 or 5 years for issued
options.

     At December 31, 1996 there were 197,635 options available for future grant.

I. RESEARCH COLLABORATION AGREEMENTS

In October 1994, the Company established a research and development
collaboration with Janssen Pharmaceutica, N.V. of Beerse, Belgium (Janssen), a
wholly owned subsidiary of Johnson & Johnson, for the discovery and development
of compounds suitable for the treatment of Alzheimer's Disease and other
neurodegenerative diseases. Under the terms of the agreements, the Company
received an initial licensing fee and Janssen will provide research funding over
a three-year research period, renewable for a fourth and fifth year. In
addition, Janssen will make milestone payments to the Company upon the
achievement of development and clinical benchmarks. The Company will receive a
royalty on sales of marketed products and Janssen will be responsible for all
development costs, including clinical trials and obtaining regulatory approval.
Deferred revenue related to these agreements was $279,095 and $806,359 at
December 31, 1995 and 1996, respectively. In October 1994, Johnson & Johnson
Development Corporation made an equity investment in the Company.

J. RESEARCH, CLINICAL TRIAL, CONSULTING AND
   LICENSE AGREEMENTS

Since beginning operations, the Company has entered into research agreements and
clinical trial agreements with universities and third parties and consulting
agreements with scientific advisors. The research agreements require the Company
to fund certain research activities, and are generally renewable on an annual
basis. In return, the Company has rights to obtain and use exclusive licenses
for the results of the research. Under license agreements with various
universities, ownership of all patents resulting from research agreements will
remain with the universities or researchers. The Company is required to incur
all costs associated with applying for and maintaining the patents. The Company
generally will obtain exclusive worldwide

                                                                              23

licensing rights and is required to remit fixed percentages, as defined, of the
net selling price of licensed products and royalties received from sublicensees
to the universities. The clinical trial agreements require the Company to fund
the performance of specific clinical procedures and the cost of administering
the clinical trials.

     As of December 31, 1996, minimum commitments under research, clinical trial
and consulting agreements are $1,162,827 for 1997 ($405,207 at December 31,
1995).

K. OTHER MATTERS

The Company is a party to a license agreement and a related sponsored research
agreement with a university that provides for a royalty of up to 5% of revenues
from products covered by these agreements. In 1995, a dispute regarding
inventorship of the ADCON(R) products and the rights of the university to
receive royalties from sales of ADCON(R) products arose between Gliatech and the
university. The university has threatened litigation regarding this dispute.
There has been no resolution of this matter. The Company is not able to make any
estimate of costs that may arise as a result of any outcomes from this dispute
and there can be no assurance that the Company will not be required to pay any
costs or royalties or that any costs to the Company, or royalties that may
result, from this dispute will not have an adverse effect on the Company.
